Yes, but also no. Through practice alone you do get better at activities while drunk, like walking or driving, but I can assure you that what two drinks did to me when I never drank vs what they do now is entirely different. My rationality stays the same now. Note that the high alcohol content will catch up to you later (you’re still dehydrated), but in the moment alcoholics are an entirely different breed a couple drinks in. If you ever hang out with people who drink regularly and those who don’t, you’ll quickly see the difference.

There are objective and measurable differences between tolerances that this post points out, though.

Hm, I thought I looked for them and didn't find them.

Reading again, yup nothing there. Just some generalities.

I guess everything is a generality if you believe hard enough.

That's an ungenerous remark, and un-called for. If there are measures in the article, then please post them. Otherwise lighten up, and cease the ad-hominem attacks.

I don't know, man. I have a friend who drinks so much it's ludicrous, and is perfectly present and functional. he is a sailor, and I have avoided situations where I see he is getting plastered (because he can get plastered, too!) and the only competent sailor on board. But he is highly functioning when drunk, I can attest to that!
